Jennifer Lopez looked red hot celebrating her 43rd birthday in New York with boyfriend Casper Smart Tuesday, and we've got the shots for you right here on Breaking Celebrity News.

The birthday girl looked spectacular (as usual) in a backless Tom Ford zipper dress, while Casper, 25, radiated a crisp, cool look in a burgundy blazer with black pants. The dancer-choreographer made sure to make J.Lo's birthday a special one by surprising her with a bash on a luxury yacht later on.

The spry Casper told Good Morning America last week that despite their 18-year age difference, coming together with J.Lo "was just very natural, you know, natural how it happened."

In the same interview, Jennifer, who was previously married to singer Marc Anthony for seven years, she could easily see herself tying the knot again.

"For me, the biggest dream is the fairy tale," the On The Floor singer said. "I will never give up on that dream."
